lNK-WELL. FOR SCHOOL-DESKS.

SPECIFICATION forming part of Letters Patent No. 372,388, dated November1, 1887.

Application filed March 12, 1887.

T aZZ whom it may concern:

Be it known that we, FRANK H. ROBERTS and ALBERT O. LUYOKX, citizens ofthe United States, residing at Detroit, in the county of XVayne andState of Michigan, have invented certain new and useful Improvements inInk- WVells for School-Desks, and we do declare the following to be afull, clear, and exact description of the invention, such as will enableothers 70 skilled in the art to which it appertains to make and use thesame, reference beinghad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of thisspecification.

Our invention relates to certain improvements in ink-wells, beingdesigned especially for school-desks.

The object of our invention is to construct asimple and cheap devicethat may be attached to the end or ends of the desk-top, and to theunder face of the same outside of the legs or supports, and in such amanner that the well may be readily attached and detached, and to allowthe well to be projected from under the 2; desktop when using, and toswing under said top when not in use, the well being so constructed thatwhen turned under the desk-top the mouth of the well will be closed toprevent evaporation of the ink; and our invention consists in theconstruction of parts, as hereinafter specified, and pointed outparticularly in the claims.

In the accompanying drawings, forming a part of the specification,Figure l is an end perspective of a school-desk containing ourinvention. Fig. 2 is an enlarged top plan showing connecting parts, themovements of which are indicated by dotted lines. Fig. 3 is an enlargedperspective of the ink bottle or well.

0 Fig. 4 is an enlarged section through desk-top and joining parts, thewell being in the posi tion shown in Fig. 1, the section taken on dottedline a; x of Fig. 2. Fig. 5 is an enlarged perspective of thetwo-partsliding gate or key.

F in the drawings represents the common standard to a school-desk, and Dthe desk or top, which is also common. On the under face of the top D,leading from the end Z, we form a channel, S, having an undercut alongits edges,

forming the sloping sides 0 0. In Fig. 5 we show a twopa rt key, Z Z,having sloping edges d d. The slant of the edges of the key coincitieswith the slant 0 of the channel formed in the top D. The united width ofthe parts of the key is equal to the width of the channel S, wherebysaid key fills snugly said channel when inserted, as shown in Figs. 1,2, and 3. lVe form in the joining edges of the parts of the key asemicircular opening having a slanting edge, 1?, so that when the partsZ Z of the key are joined a flaring hole is formed through the key.

In Fig. 3 we show the ink-well, which we make, preferably, of glass.Said well is provided with the circular mouth at forfllling and for theinsertion of the pen. 0 is the chamher. a is the neck, which we makesolid, and is of the form of an inverted cone having the inclinedannular-side a, with annular flanges a. The incline of the neck acorresponds with the incline t of the gate, and the neck a is madesuffioiently large to fill the opening formed in the two-part gate Z Z.When said parts of the gate are placed around the neck, as shown inFigs. 2 and 4, the length of the neck a and the thickness .of the gateare the same. By this construction, when the gate Z Z is forced into thechannel S, the neck a will slide with said gate into it, as shown inFig. 4, whereby the well becomes suspended under the desk-top, do andmay be turned about on the neck a, journaled in the gate, and to removethe well from the desk-top you simply withdraw the gate.

Around the mouth at of the well we form an annular recess, 6, ordepression, (see Fig. 3,) and filling said annular recess is a rubberring, R, which is held in position by the annular recess. The upper edgeof the ring R comes slightly above the end of mouth'm of the well. Itwill be observed that by this arrangement 0 when the well WV is swungaround, as shown in Figs. 1 and 4, the rubber ring R is forced againstthe under face of the desk-top, thus closing the mouth of the well,preventing the ink from evaporating when the well is not in use. It willbe observed, also, that the well W is U shaped, and as it is journaledin the sliding gate to project the well, so as to insert the swingaround under the desk-top out of the.

way without injuring the well; and to remove the well the drawingoutward on the gate to the dotted position in Fig. 2 will detach thewell from the desktop. as hereinbefore stated, when the well can becleaned out or emptied of its ink.

-VVe have shown arubbcr ring'around the mouth of the well, so as toclose the mouth when swung under the desktop and to make it air-tight.The same result may be accomplished by placing a strip of rubber on theunder face of the desk-top over the swinging point of the mouth, asshown at 3 to the right of Fig. 4, and swinging the mouth of the wellunder it; or any flexible material-such as leather or felti ng-may be soemployed, whereby we are able to dispense with the rubber ring R.Therefore we desire our invention to cover such changes.

Having thus fully set forth our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. In combination with the desktop and its standard, the chamber formedin the under face of the top, the two part key having the centralopening, the ink-well journaled in said two-part key and having theconical lug, and the annular recess formed around the mouth of the well,with rubber or flexible ring located in said chamber, as and for thepurposes set forth.

- 2. In combination with the desktop, the U- shaped ink-well having theneck it, said neck being journaled in the under face of the desktop,whereby the mouth m of the well may be swung under the top or projectedtherefrom, as and for the purposes specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
